Subject: Re: Fairlie A78

The main queries and concerns regarding the eefictoveness of traffic calming measures are:

  1.  Effectiveness of the traffic lights and traffic calming measures. The new traffic lights and vehicle activated signs have been successful at most locations. The speed activated signals are working effectively in that they are activating on detection of speeding vehicles. However the average speeds have marginally increased at the north and south gateways which is disappointing. This will require further investigation to determine which additional measures will alleviate this trend.

– how has speed been reduced along the length of Fairlie’s A78 road since the speed activated lights were installed? Evidence has shown that overall the schemes have had a positive impact on vehicle speeds with a negligible increase in red light running at the traffic signals. There have been no accidents at the junction since the scheme was introduced.

–  traffic light jumps or speeding – can camera data be captured to lead to prosecutions? Villagers are surprised the camera activation doesn’t inform Police etc. There has been a negligible (0.0389% of vehicles) increase in red light running at the traffic signals from stud detection and video analysis. At this time the data gathered in relation to the traffic signals and red light runners does not record details of the individual vehicles and therefore cannot be used for prosecution purposes. The operation of the traffic signal and data gathered has been by the use of intelligent stud technology which does not identify vehicles. At this time there are no plans to introduce red light running cameras at this location.

– time, volume, speed analysis at the various points of the A78 previously used; are traffic speeds sufficiently lower across the whole 30 mph A78 stretch? A recently produced report into the effectiveness of the scheme contains detailed information captured along the route. As previously stated, on the whole, vehicle speeds have reduced.

– options for slowing down traffic as it enters and leaves the village at both north and south sides on A78. Recent results into the effectiveness of the scheme indicate that investigation will be required to seek further measures to deter vehicle speed at the north and south sides of the village.

  1.  Housing Developments under construction

– Dawn Homes development for approximately 120 new homes loacted next to BP garage (app 112 main Street) on A78 ; what traffic calming/management measures should be put in place at the A78 intersection.  This junction is very near the primary school near where roads opposite intersect the A78.   This area of the road already becomes congested at peak times.

I have spoken to our Development control colleagues and they provided me with an overall site plan. The design plan includes recommendations for a new right turning lane on the A78 trunk road at the junction with the housing development. The inclusion of a right turning lane is standard design practise with a development of this size, to minimise traffic congestion by removing queuing traffic on the trunk road and also maintaining a level of safety for right turning vehicles. I am back in the office on Monday 9th January if you have any further queries about the development.

Further questions for Neil will be discussed at the next FCC on the 6th February 2017.
